Abstract
The striking mechanism for a watch includes a gong, which is connected to a gong-carrier, a hammer for striking the gong at pre-determined times, a damper counterspring for keeping the hammer at a distance from the gong in an idle mode, and a hammer drive spring, which includes a fixed end and an end that is free to move. The striking mechanism includes a locking device, which is provided with at least one rotating bolt. This bolt includes a first arm provided with a hook for hooking onto a notch of the hammer to lock the hammer in an idle mode. The locking device is arranged to lock the hammer following a single strike of the hammer against the gong in a strike mode.

A watch striking mechanism, the mechanism including:
- a gong, which is connected to a gong-carrier,
- a hammer for striking the gong at predetermined times,
- a damper counterspring for keeping the hammer at a distance from the gong in an idle mode, and
- a drive spring for the hammer, which includes a fixed end and an end that is free to move, said drive spring being able to be wound to drive said hammer against the gong in a strike mode in order to produce an acoustic sound,
- wherein the striking mechanism includes a locking device provided with at least one bolt, which is intended to lock the hammer in an idle mode, and to be moved away from the hammer in a strike mode, when the drive spring is wound, the locking device being arranged such that the drive spring drives the hammer to strike the gong for a first time before the bolt locks the hammer in the idle position following the first strike.
